The underrating of Luck is pretty comical (as is the idea that Wilson is head and shoulders above the young QB class).
In Luck's situation, he was asked to throw the ball downfield the most of all starting QBs (not just the young pups). He did not benefit from an elite OL, running game and/or defense like Kaepernick, Wilson, or Griffin. People like to downplay Alex Smith's passer rating for being short passing game and very little risks downfield.....well, same principle here basically as compared to Luck, all of these QBs kept the ball "safe and efficient".
While Luck did not have the best rookie season statistically, he did have the most wins ever, shattering his predecessor's record of 7 or 8 wins with 11. I get that Indy had a last place schedule, but regardless teams with last place schedules very rarely win 11 games (let alone with a rookie QB).
His mobility is excellent for a guy not named Wilson, Griffin, Kaepernick, and
Vick. He's a little faster than Aaron Rodgers and Alex Smith, two pocket passer QBs that can move pretty well.
As for Wilson, he's a great QB. But it's too early to tell how he ranks against the rest.
